implement Clone for Box<str>, closes #27323
This is a minor [breaking-change], as it changes what `boxed_str.to_owned()` does (previously it would deref to `&str` and call `to_owned` on that to get a `String`). However `Box<str>` is such an exceptionally rare type that this is not expected to be a serious concern. Also a `Box<str>` can be freely converted to a `String` to obtain the previous behaviour anyway.
